Answer:
The bivalve foot becomes proportionately larger in smaller individuals
Explanation:
The bivalve foot is a muscular appendage that enables the animals to dig in across the sandy surfaces. This structure is adapted to life stile and movement, being reduced in animals like oysters that live permanently attached to the rocks
Sedimentary rock is the most likely. Igneous and metamorphic rocks go through too much pressure and heat for fossils to be preserved. The bones would just melt away.
When you see butterflies with different wing colors, you should conclude that there's a difference in their protein expression, so there's a mutation somewhere in the genome of the butterfly with the new color.
To answer the first question, if the desired color exists in nature, you should take the specific butterfly's caterpillars and raise them. If the desired <span>butterfly color doesn't exist in nature than you should wait for the mutation to occur (which could take many years) or look for the gene in the butterfly which is responsible for the pigmentation of their wings.

For the second question, mutations in the gene of the coloration of the butterfly's wing could change the color, so what scientist do is to try to provoke different mutations on the caterpillar's gene until they have a butterfly with the desired color.
So everything is about molecular genetics, every difference between species is due to mutations.
The Sun, like others stars, is a ball of gas. In terms of the number of atoms, it is made of 91.0% hydrogen and 8.9% helium. By mass, the Sun is about 70.6% hydrogen and 27.4% helium.
A least common multiple the lowest common factor that the two numbers have in common. Hope this helps. :)
